Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Diet and breeding
The female lays two white eggs in a tree hole, then seals herself in by blocking the entrance to the nest with droppings, debris and mud. The male, and other adults and young forming a cooperative group, feed the breeding female and the chicks through a narrow hole.
The female breaks the "wall" and leaves the nest when the chicks are able to fly.
In crisis
Due to this, the white-crowned hornbill was uplisted from near threatened to endangered on the IUCN Red List in 2018.
CITES lists this taxon on Appendix II. Confirm the current appendix on the CITES checklist.
